Philosophical approaches to the ›extended mind‹, most rigorously advocated in recent years by Andy Clark, centre around the idea that human mentality is constitutively dependent upon external structures functioning as indispensable »scaffolds« of cognitive processes. In particular, a broad range of tools such as computers, calculators, symbol systems as well as a host of external storage devices have been invoked as cognitive extensions. However, so far, neither the nature of more complex and distributed social structures, arrangements and institutions relevant to cognitive extensions, nor the domain of emotion has received sufficient attention.
